nonparam_match_empirical_cdf
(initial_array, target_array)¶ Matches the empirical CDF of the initial array with the empirical CDF of a target array. Initial ranks are conserved, but empirical distribution matches the target one. Zero-pixels (i.e. pixels having the minimum value) in the initial array are conserved.
Parameters: - initial_array : array_like
The initial array whose CDF is to be matched with the target.
- target_array : array_like
The target array.
Returns: - output_array : ndarray
The matched array of the same shape as the initial array.
